RECORDING SPEEDOMETER.

Specification of Letters Patent. I Patented July 18, 1922.

Application filed August 15,1921. Serial No. 492,313.

ometersand to the recordsheets for use in connection therewith.

An object of my invention is to provide a recording speedometer and sheet therefor whereby it is possible to note the speed at which the vehicle was driven between any points, and whereby the trip or season mileage may at any time be readily ascertained.

A further object is to provide, in a recording speedometer, means for driving both a feed roller-and a reel upon which the recording sheet is wound-and to operate both drives from the one which. drives the governor. ()ther objects may be ascertained from a study of the following specification and claims and the accompanying drawings, wherein my invention is shown in its present preferred form.

My invention comprises those novel parts and combinations thereof which are shown in the accompanying drawings, described in the specification, and particularly defined by the claims which terminate the same.

Figure l is a front elevation of my device as it would appear to the driver of the car.

Figure 2 is a central section through my device.

Figure 3 is a rear view thereof with the casing shown in sectign.

A governor 1 of any suitable form, and herein shown as a rotative ring,'is secured upon and rotated by a shaft 10 which is connected by a flexible shaft (not shown) to the'running gear of the vehicle. A sleeve 11 is secured upon the upper end of the shaft '1 and is connected with the governor l to be controlled thereby in-its position axially of the shaft 10. At its upper end the sleeve 11 is provided with grooves which are shown at 12 and which form in effect a cylindrical rack. A pinion 13 meshing therewith ro-.

tat-es its shaft upon which is secured a 'second pinion l kes the collar 11 is raised or lowered, and this'pinion 14L communicatesits movement through a segment gear'15 to a pointer 16 which is pivoted in the casing at 17 and which is, provided with an ink reservoir forming a marker 18.

A record sheet 2 is normally carried upon a supply roll 20. It is wound thence upon a reel 21, passing overguide rolls 22 and a table 23 positioned beneath the marker 18.

The sheet 2 I have shown as provided with a series of holes 24 adjacent its edge by means of which it is engaged with teeth 32 upon the feed roller 3 to be advanced.

Any suitable drive for the reel 21 and the feed roller 3 may be employed. I have shown this as including skew gears 31 by means of which a shaft 34 is rotated from the governor shaft 10, a pinion and gear 33, and bevel gears 35 which drive a counter shaft 36. The feed rollers 3 are connected With the counter shaft 36 through skew gears 37 and the reel 21 is driven from the same counter shaft through the bevel gears .38. The reel 21 is loosely mounted upon a shaft 39 driven from the bevel gears 38 and is connected therewith by a frictional drive connection shown herein as the spring washer '25. A spring washer 26 engages the supply reel 20 to act as a drag thereupon. The drive of the reel 21 is slightly more rapid than the drive of the feed rollers 3 so that the reel has an overdrive. Any excess is taken up by slippage of the frictional drive connection.

Upon the face of the record sheet 2 I provide a plurality of columns 4 of figures. These are spaced longitudinally of the sheet by' an amount equal to the distance the sheet is advanced during a given advance of the vehicle. For instance, the figures may be spaced to represent a mile. Each succeeding column of figures is so arranged that its first figure lies opposite the second ure in the next preceding column. Thus no two columns have a common zero, transversely of the record sheet. The sheet may also have a column {ll of figures which represent the season mileage, these being placed preferably atan edge of the sheet.

At the start of a trip the driver will note what numeral in the first column at the left is beneath the pointer 16, or its lateral point 19, as the pointer lies in its rest position. At the beginning of the trip which has just begun, as is shown by the record in Figure 1, the point 19 was above the numeral ten.

Therefore the tenth column following the first, that 1s, the eleventh column, is selected as the one in which the trip mileage Q7 Leaaeeo is to be read. This column is selected because it is the only one opposite, or in the same row as the numeral ten, which contains the numeral twelve, corresponding to a zero, the same as the numeral twelve upon a. clock face represents zero or the starting point. If the point 19 Were above numeral three of the first column at the left when in its rest position, the 'fourth column would be selected, as that column has its numeral twelve, or zero, opposite the pointer.

In order to remember throughout the trip that the eleventh row of figures is being employed to indicate mileage traversed, I may employ a roller 5 controlled-by a knob or handle 51 and having thereon a series of figures corresponding to the figures in each row it. This may be then turned up to show the figure 11 through a window 52 in the outer casing. Thereafter, throughout the trip when it is desired to know the mileage traversed, byreterring to the eleventh row of figures this may be read directly. If desired, a row 53 0t figures may be placed upon the casing to denote the various rows. Obviously, many additional columns may be provided, permitting many more figures in any one column.

Another row 54 of figures may be placed beneath the end of the pointer 16, these indicating the rate of speed at which the vehicle is traveling. As the vehicle progresses, the marker 18 indicates by a wavy line upon the record sheet 2 the starting and stopping points. and the rate of speed in between at all times. This furnishes a permanent record for the owner of the car.

What ll 'claim as my invention is:

1. In a recording speedometer, the combination of a movable sheet and a transversely movable pointer, said sheet having thereon a plurality of individual transversely-spaced lines of figures indicating distances traveled, the several lines having their Zero points positioned differently from all other lines, longitudinally of the sheet.

2. In a recording speedometer, the combination of a longitudinally movable sheet and a transversely movable pointer, said sheet having thereon a plurality of transversely spaced, longitudinally extending lines of figures indicating distances traveled, each succeeding line of figures being dropped to bring its first unit opposite the second unit of the next preceding line.

3. In a recording speedometer, the combination of a longitudinally movable sheet and a transversely movable pointer, said sheet having thereon a plurality of transversely-spaced lines of figures indicating distances traveled, the several lines having their zero points positioned differently from all other lines, longitudinally of the sheet, and an indicator settable to indicate the particular line of figures which is to be used.

4. In a recording speedometer, the combination of a longitudinally movable sheet and a transversely movable pointer, said sheet having-thereon a plurality of transversely-spaced lines of figures indicating distances traveled, the several lines having their zero points positioned differently from all other lines, longitudinally of the sheet, means whereby the various lines may be distinguished, and an indicator settable to indicate the particular line being used.

Signed at Seattle, King County, Washington, this 9th day of August, 1921.
